A Scoping Review of Human Trafficking Screening and Response

Service providers are increasingly asked to identify individuals who are experiencing trafficking and to connect them with resources and support. Nonetheless, identification is complicated by the reality that those who are experiencing trafficking may rarely self-identify, and providers may fail to identify individuals who are experiencing trafficking due to lack of guidance on how to screen for trafficking capably and sensitively. With the aim of guiding practice, we undertook a scoping review to search for and synthesize trafficking screening tools and response protocols. Following the PRISMA extension for Scoping Reviews (PRISMA-ScR), we located 22 screening tools contained in 26 sources. We included any documents that described or tested human trafficking screening tools, screening or identification protocols, response protocols, or guidelines that were published in any year. All documents were abstracted using a standardized form. Key findings showed that most tools were developed by practice-based and non-governmental organizations located in the U.S. and were administered in the U.S. Few screening tools have been rigorously evaluated. The common types of screening questions and prompts included (a) work conditions; (b) living conditions; (c) physical health; (d) travel, immigration, and movement; (e) appearance and presentation; (f) mental health, trauma, and substance abuse; (g) associations and possessions; and (h) arrests and prior involvement with law enforcement. We were not able to locate specific response protocols that provided step-by-step guidance. Nonetheless, the review revealed available practice-based and research-based evidence to help inform guidance concerning how screening and identification of human trafficking may be administered.
